Threshing load sensor (24) as shown in the flow chart
When the detected value is out of the setting range of the cylinder load and the load is excessive, the shift motor (28) is driven forward by the output of the control circuit (26) to rotate the traveling speed change lever (20) to the deceleration side. When the load is too small, the motor (28) is reversely driven by the output of the control circuit (26) to rotate the traveling speed change lever (20) to the speed increasing side, so that the handle load, that is, the work load is within the set range. The vehicle speed is automatically reduced or increased.
When the detection value of the sensor (24) is within the range of the cylinder load setting range, the speed increasing switch (3) is operated by operating the vehicle speed adjusting lever (29).
0) Alternatively, when the deceleration switch (31) is turned on, similarly to the above, the motor (28) is driven in reverse or forward by the output of the previous control circuit (26) to drive the traveling speed change lever (20).
